First off, I don’t have any real training or professional knowledge of the things I attempt to scrap together. That being said, there’s no better way to learn!
Anyway, first up.
Peltier beer coaster! I currently own this Peltier unit: It’s a 12V thermoelectric cooler. It gets hot on one side, and cold on the other. I have yet to test it out, because I need to attach a heatsink to the hot side, to prevent it from burning itself to death. I thought I had a spare, but it looks like I need another. So here I wait.
In the mean time, I’ve picked up what I’ll use as the cooling plate. Ideally I’d like to use something aesthetically pleasing, but for now I’ve got a square steel electrical box plate I picked up at Home Depot for $0.50. It act as the actual coaster that *should* keep the beer cold that I place on top of it.
I have quite a few power supplies laying around that are 12V, and under the Peltier unit’s amperage rating. I would like to have a variable power supply, but as far as I can tell, they’re pretty pricy.
Hopefully I can get around to this on my next day off and post it here!
